Can’T Bear It! Employing Culturally Sensitive Initiatives To Reduce Bear Bile Demand In Northern Vietnam, Alicia Ngo, Shannon Randolph
Can’T Bear It! Employing Culturally Sensitive Initiatives To Reduce Bear Bile Demand In Northern Vietnam, Alicia Ngo, Shannon Randolph
EnviroLab Asia
Over the past 30 years, the combination of overhunting, habitat loss, and increased bear bile demand has caused significant declines in Asiatic black bear (aka moon bear; Ursus thibetanus) and sun bear (Helarctos malayanus) populations. In Eastern medicine, bear bile is extracted from the gallbladders of bears and is then used to treat a wide range of inflammatory, liver, and degenerative ailments. However, the use of bear bile has had significant impacts on bear populations. Given that communities in Northern Vietnam have a lengthy history of using bear bile and bear bile is easily accessible, merely advocating for wildlife conservation ...
Modeling The Ecological Dynamics Of A ThreeSpecies Fish Population In The Chesapeake Bay, Iordanka N. Panayotova, Maila B. Hallare
Modeling The Ecological Dynamics Of A ThreeSpecies Fish Population In The Chesapeake Bay, Iordanka N. Panayotova, Maila B. Hallare
CODEE Journal
We present an inquirybased project that is designed for a mathematical modeling class of undergraduate junior or senior students. It discusses a threespecies mathematical model that simulates the biological interactions among three important fish species in the Chesapeake Bay: the prey Atlantic menhaden and its two competing predators, the striped bass and the nonnative blue catfish. The model also considers the following ecological issues related to these three species: the overfishing of menhaden, the invasiveness of the blue catfish, and the harvesting of blue catfish as a method to control the population. A series of modeling scenarios are considered based ...
Qualitative Analysis Of A Resource Management Model And Its Application To The Past And Future Of Endangered Whale Populations, Glenn Ledder
Qualitative Analysis Of A Resource Management Model And Its Application To The Past And Future Of Endangered Whale Populations, Glenn Ledder
CODEE Journal
Observed whale dynamics show drastic historical population declines, some of which have not been reversed in spite of restrictions on harvesting. This phenomenon is not explained by traditional predator prey models, but we can do better by using models that incorporate more sophisticated assumptions about consumerresource interaction. To that end, we derive the Holling type 3 consumption rate model and use it in a onevariable differential equation obtained by treating the predator population in a predatorprey model as a parameter rather than a dynamic variable. The resulting model produces dynamics in which low and high consumption levels lead to single ...

Engaging Students Early By Internationalizing The Undergraduate Calculus Course, Chinenye Ofodile
CODEE Journal
Today's world is global. However, despite increasing numbers and diversity of participants in Study Abroad programs, only 10% of U. S. college students get that experience. There is an evergrowing need for students to become aware of and experience other cultures, to understand why others think and act differently. Internationalization is the conscious effort, begun nearly 40 years ago, to integrate an international, intercultural, and global dimension into the purpose, functions, and delivery of postsecondary education.
Albany State University began a Global Program Initiative in the 1990s. In 2016, we extended into mathematics the curriculum innovations of this program ...
Facing The Pandemic Together: Forming A Collaborative Research Group, Michael C. Barg
Facing The Pandemic Together: Forming A Collaborative Research Group, Michael C. Barg
CODEE Journal
This is an account of how a reading and writing project in an introductory differential equations course was transitioned to a professorstudent research group collaborative project, in response to the global COVID19 pandemic. Adapting on the fly to the everevolving pandemic, we collected data, estimated parameters in our models, and computed numerical solutions to SIRbased systems of differential equations. This is a description of what we did and how we found comfort in the project in this time of great uncertainty. The collaboration yielded successes and more questions than we had answers for, but the situation provided an opportunity of ...

Epidemiology And The Sir Model: Historical Context To Modern Applications, Francesca Bernardi, Manuchehr Aminian
CODEE Journal
We suggest the use of historical documents and primary sources, as well as data and articles from recent events, to teach students about mathematical epidemiology. We propose a project suitable  in different versions  as part of a class syllabus, as an undergraduate research project, and as an extra credit assignment. Throughout this project, students explore mathematical, historical, and sociological aspects of the SIR model and approach data analysis and interpretation. Based on their work, students form opinions on public health decisions and related consequences. Feedback from students has been encouraging.
We begin our project by having students read excerpts of ...

Deterministic Republic, Kris H. Green
Journal of Humanistic Mathematics
This story is an extension of the paper "Mathematics and Voter Choice" published in this same issue of the Journal of Humanistic Mathematics. It explores what elections and politics might look like from the voter perspective if some of the ideas from the paper were implemented. The story is also an attempt to highlight how mathematics and data science are done, much the way a colleague of mine refers to shows like CSI as recruiting tools that use "dramatic pipetting" in the labs to show daytoday science in action. The story is, as you will no doubt see, heavily influenced ...

“You Will Remain Unwavering In Your Determination To Succeed No Matter How Long It Takes”: A MathematicoEmotional Analysis Of A Guide To Higher Learning, Kathleen M. Clark, Oksana M. Rubis
Journal of Humanistic Mathematics
In this article we present an analysis of the multifold artist’s book, A Guide to Higher Learning (Chen, 2009). In our analysis, we propose different perspectives from which to view the mathematical and philosophical aspects found within the book. We explore aspects of “higher learning” by analyzing the complex mathematical equations and textual elements that readers meet in the book. Chen challenges the reader with: “This is a test. You will not be given any assistance or instructions on how to proceed. You will not be told when to begin or when to stop” (Chen, 2009). Thus, in our ...
Aligning Political Options And Aggregated Personal Opinions On The Issues, Kris H. Green
Aligning Political Options And Aggregated Personal Opinions On The Issues, Kris H. Green
Journal of Humanistic Mathematics
Much work has been done in studying how to aggregate voter opinions to decide a fair election. These models presuppose that each voter has a solid understanding of their choices and can express that opinion in the election process. We discuss why this is not always the case. Further, we explore some of the issues that arise when considering the multidimensional nature of both voter preference, with respect to the slate of issues in an election, and the platforms of the various candidates, with respect to the same slate of issues. In light of the complications we encounter and with ...

Computational Thinking In Mathematics And Computer Science: What Programming Does To Your Head, Al Cuoco, E. Paul Goldenberg
Computational Thinking In Mathematics And Computer Science: What Programming Does To Your Head, Al Cuoco, E. Paul Goldenberg
Journal of Humanistic Mathematics
How you think about a phenomenon certainly influences how you create a program to model it. The main point of this essay is that the influence goes both ways: creating programs influences how you think. The programs we are talking about are not just the ones we write for a computer. Programs can be implemented on a computer or with physical devices or in your mind. The implementation can bring your ideas to life. Often, though, the implementation and the ideas develop in tandem, each acting as a mirror on the other. We describe an example of how programming and ...
Teaching From The Unknown, Jon Jacobsen
Teaching From The Unknown, Jon Jacobsen
Journal of Humanistic Mathematics
The goal of teaching is to transform our students' understanding, much as the goal of acting is to transform the audience's reality. In this article we use the context of mathematics to explore connections between teaching and acting and how such connections can help our students learn not only mathematics, but about the nature of mathematics.
Using Mathematical Equations To Communicate And Think About Karma, Kien H. Lim, Christopher Yakes
Using Mathematical Equations To Communicate And Think About Karma, Kien H. Lim, Christopher Yakes
Journal of Humanistic Mathematics
Two equations are presented in this article to communicate a particular understanding of karma. The first equation relates future experiences to past and present actions. Although the equation uses variables and mathematical symbols such as the integral sign and summation symbol, it reads more like a literal translation of an English sentence. Based on the key idea in the first equation, a second equation is then created to highlight the viability of using math to communicate concepts that are not readily quantifiable. Analyzing such equations can stimulate thinking, enhance understanding of spiritual concepts, raise issues, and uncover tensions between our ...

RealWorld Modelling To Increase Mathematical Creativity, Robert Weinhandl, Zsolt Lavicza
Journal of Humanistic Mathematics
Modelling could be characterised as one of the core activities in mathematics education. However, when learning and teaching mathematics, mathematical modelling is mostly used to apply and deepen mathematical knowledge and competencies. Our educational study aims to explore how mathematical modelling, using real objects and highquality mathematical technologies, could be utilised to acquire mathematical knowledge and competencies, and how learners could creatively use their existing knowledge. To discover the potential of mathematical modelling using real objects and highquality mathematical technologies to acquire mathematical knowledge and competencies, and to stimulate learners' creativity, first, we combined cognitive and creative spirals and mathematical ...
A HeartCentered Stance: Receptivity To Algebra Teachers’ And Students’ Multidimensional Experiences, Nicole L. Fonger
A HeartCentered Stance: Receptivity To Algebra Teachers’ And Students’ Multidimensional Experiences, Nicole L. Fonger
Journal of Humanistic Mathematics
The algebra classroom in urban public high schools in the United States is a complex space, ripe with many challenges and opportunities. In this paper I introduce the notion of a heartcentered stance for the teacher and the educator, and a method of engaging in creative expression for reflection and introspection toward individual change in the rich context of the high school algebra classroom. My evolving relationships with two high school algebra teachers, observations of their classrooms, as well as my own selfstudy and professional growth, are incorporated into this paper as I introduce and exemplify two tenets of a ...

In closing I end with some recommendations for interesting research directions in the field of mathematics education.
The Prime Number Theorem As A Capstone In A Complex Analysis Course, Stephan Ramon Garcia
The Prime Number Theorem As A Capstone In A Complex Analysis Course, Stephan Ramon Garcia
Journal of Humanistic Mathematics
We present a detailed proof of the prime number theorem suitable for a typical undergraduate or graduatelevel complex analysis course. Our presentation is particularly useful for any instructor who seeks to use the prime number theorem for a series of capstone lectures, a scaffold for a series of guided exercises, or as a framework for an inquirybased course. We require almost no knowledge of number theory, for our aim is to make a complete proof of the prime number theorem widely accessible to complex analysis instructors and their students. In particular, we highlight the potential pitfalls and subtleties that may ...

Mathematical Representations In Magazine Advertisements: Have The Messages Changed In A Decade?, Jennifer Hall
Journal of Humanistic Mathematics
Although people's ideas about mathematics and mathematicians often develop from their school and home experiences, such ideas also are influenced by interactions with popular media. In this article, I report on findings from a study in which I analyzed magazine advertisements for representations of mathematics and mathematicians. Data collection took place in two phases, approximately a decade apart. In each phase, I reviewed a year’s worth of issues in each of six diverse, popular magazines for mathematical representations in advertisements. The frequency of mathematical advertisements decreased from Phase 1 to Phase 2, but the initial frequency was already ...
